Možnosti biomonitoringu atmosférických podmínek pomocí mechorostů v průmyslem ovlivněném regionu.

Abstract

This thesis presents the outcomes of research of possibilities of using bryophytes in the field of biomonitoring/bioindication of the atmospheric state. Utilization of 3D photogrammetric scanner was evaluated in order to assess its suitability for the moss canopy structure analysis. This approach was further compared to the LED laser scanner and relation of the canopy structure to the environmental factors (humidity, temperature) was assessed. 3D photogrammetric scanner, unlike LED laser scanner, allows us to gather date in real time and with up to thousand-times higher accuracy. Multiple regression analysis of the relation between humidity, temperature and canopy structure showed significant dependence. Thus, canopy structure is a reflection of the particular moss population history and can be used as indicator of these atmospheric conditions in its vicinity Furthermore, this thesis presents the comparison of active biomonitoring of atmospheric trace elements ((Al, As, Cd, Cr, Cu, Fe, Hg, Pb, V a Zn) by the means of “irrigated moss bag” method and common technical methods used by Czech Hydrometeorological Institute. Effects of concentration of the trace elements in suspended dust particles, humidity, temperature and irradiance on their accumulation in the moss material were assessed as well. By the means of multivariate analysis, models describing such dependence were created.
